1. A safety mirror lens assembly including a mirror unit, the mirror unit comprising:
- a mirror lens having a reflective outer surface and a rear surface, the mirror lens comprising a mirror lens body, the mirror lens body terminating in an oval shape peripheral edge that surrounds the reflective surface, the mirror lens body being a three-dimensional, substantially convex body having a major axis of first length and a minor axis which intersects the major axis and has a second length, the major axis and the minor axis being defined in a plane that contains the oval shape peripheral edge, the outer mirror surface having a first constant radius of curvature along a first line thereof which coincides with the major axis and having a second, constant radius of curvature on the outer surface thereof along a second line which coincides with the minor axis of the lens, said first constant radius of curvature being substantially larger than said second constant radius of curvature; and
a mirror assembly structure including a mirror back adjacent the continuous peripheral edge of the mirror lens;
a fastening structure for fastening the mirror back to the mirror lens; and
a coupling structure attached to the mirror back, the coupling structure including hardware for engaging a mirror pole which serves to attach the mirror unit to a vehicle body in a manner which allows the orientation of the mirror lens to be adjusted.

Abstract
A safety mirror lens assembly includes a mirror unit with a mirror lens that has a three-dimensional convex/ellipsoid reflective surface which terminates in an oval shape peripheral edge. The reflective surface is such that a notional line traced to coincides with the major axis has a first constant radius of curvature and a second notional line traced to coincide with the minor axis has a second constant radius of curvature. The first radius of curvature is substantially greater than the second radius of curvature. The mirror lens is usable for a cross-over mirror for a vehicle, for example, a school bus.

12. A safety mirror lens assembly including a mirror unit, the mirror unit comprising:
-
a mirror lens having a reflective outer surface and a rear surface, the mirror lens comprising a mirror lens body which is dome-shaped and has a circular peripheral edge that surrounds the reflective surface, the mirror lens body being a three-dimensional, substantially spherical body that is symmetrical relative to a vertical axis, the outer mirror surface having a constant radius of curvature along any trace line thereof which begins at a first point on the peripheral edge and terminates on second point on the peripheral edge and said any trace line also lies in a plane which contains the vertical axis, each one of said any trace line having the same constant radius of curvature; and
a mirror assembly structure including a mirror back adjacent the continuous peripheral edge of the mirror lens;
a fastening structure for fastening the mirror back to the mirror lens; and
a coupling structure attached to the mirror back, the coupling structure including hardware for engaging a mirror pole which serves to attach the mirror unit to a vehicle body in a manner which allows the orientation of the mirror lens to be adjusted.
